Snapshot doesn't work, right?

[lure]

module "ebs_csi_driver_controller" {
  source  = "DrFaust92/ebs-csi-driver/kubernetes"
  version = "3.3.1"

  enable_volume_snapshot = true
  enable_volume_resizing = true
  enable_default_fstype  = true

  ebs_csi_controller_role_name               = "${var.cluster_name}-ebs-csi-driver-controller"
  ebs_csi_controller_role_policy_name_prefix = "${var.cluster_name}-ebs-csi-driver-policy"
  oidc_url                                   = module.eks.cluster_oidc_issuer_url

  tags = local.tags
}

it does not install the CRD and it seems to install csi-snapshotter only ? In the official doc there are 3 containers... And the https://github.com/kubernetes-sigs/aws-ebs-csi-driver/tree/master/examples/kubernetes/snapshot manual does not work.
